Personal digital assistants (PDA) are handheld devices that can serve different functions. Many PDAs can access the Internet or intranet via WiFi, Bluetooth, or wireless wide or local area networks. Software may be downloaded to support functionality; these devices may be used for a wide range of applications, including digital note taking, electronic textbooks, and file sharing. Some school systems have begun to use PDAs as administrative tools or integrate them into classroom learning.

The supported applications and type of connection will determine bandwidth requirements for the devices (Roseberry, 2007). The use of PDAs as classroom or administrative tools should be considered when designing a wireless network.
